Substitute?

  Yeah, it was just another gym class. We were doing volleyball. The Evil Orange Ball hasn't been active lately. I'm too smart to think that it has given up just yet.
  So I was just playing volleyball with my partner, and out of nowhere, an (evil) purple ball shoots through the air and strikes someone in the head.
  It rolled over to me, and I kicked it. I don't know if The Evil Orange Ball is still trying to get rid of me and people, but all I know is that I now have to watch out for The Evil Purple Ball too. Who knows what'll happen next.
